Fig. 1From: The sensitivity of median versus ulnar palmar mixed nerve study in the early diagnosis of carpal tunnel syndromeControl group at the left showed normal neurophysiological parameters of median, ulnar motor, and sensory studies; normal 4 comparative tests. CTS group at the right showed normal neurophysiological parameters of median, ulnar motor, and sensory studies; abnormal LM-IN (> 0.5); abnormal MVR (>0.4); abnormal Mix U-M (>0.4); and normal MVU (≤0.5). The traces from above downwards [median motor wrist, elbow, and palm (control only), LM-IN (2 traces), routine median sensory, MVR(2 traces), Mix M-U (2 traces), routine ulnar sensory, and MVU (last 2 traces)Back to article page
